The solution of the differential equation e ^ ( d y ~d x ) =x+1 ; y(0)=5 , x (-1, )
Options
- A(x-1) (x+1)-x-5=y
- B(x+1) (x+1)+x+5=y
- C(x-1) (x+1)+x-5=y
- D(x+1) (x+1)-x+5=y
Correct answer
D. (x+1) (x+1)-x+5=y
Step-by-step solution
aligned & e ^ d y ~d x =x+1 & d y ~d x = _ e (x+1) & d y= _ e (x+1) d x & y=(x+1) _ e (x+1)-(x+1)+C [integrating by parts] & putting x=0 and y=5 we get C=6 & y=(x+1) _ e (x+1)-x+5 aligned
